Patented Apr. 14, 1942 snacrnlc moN CONSTRUCTION S. Braun, Strasburg, Ohio, assignor to AKmmp-ltionarch Company, St. Louis, Mo., a

corporation of Missouri application March 2s, 193s, serial No. 158,544 t -s claims. l (cl. as-so) Y My vinvention relates to electric appliances and attachmentstherefor and particularly thosey used ons'adirons or such other appliances as may be subjected to a high degree of heat.

Among th'e objects of myin'vention is the provision of a new and' improved appliance construction which is of simple rugged construction and relatively inexpensive to manufacture..

yAnother object of my invention 4is the provision of a new and improved sadiron or the like which is,constructed so as to take advantage of a variety of-heat insulating features which can be built into thev device in order to increase its convenience in use while at the same time reducing the cost and number of operations necessary to manufacture it. Another object is the provision of a sadiron wherein the handle grip comprising an insulating material is secured to the main portion of the iron by means of handle brackets which themselves are so constructedr that they not only insulate the handle grip from `the iron portion, but are instrumental in rapidly dissipating heat so that in many instances the brackets themselves are reasonably cool when the iron is in operation. Y

Another object is the provision of a new and improved sadiron wherein an extension of theV handle grip forms one of the supports for holding the iron in an upended position.

With 'these and other objects in view. my invention consists in the, construction, arrangement and combination of the various parts ofmy device whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims and illustrated in the accompanying drawing, in which:

Figure 1 is a perspective view of the iron completely assembled with allparts in place.

Figure 2 is an enlarged vertical elevation partly in section showing the various attachmentsl in place. y

Figure 3 is a vertical side elevation.

In the construction of electrical appliances it is always necessary-to consider the heating factor and|to sn insulate the appliancethat it may be rested upon a table or other surface without damaging the surface by reason of bringing excessive heat into contact .with it or if the appliance is to be lifted or handled, handle means must be provided which are eectively insulated from the body of the appliance so thatk the user will not b'e burned when the appliance is being manipulated. It must also be borne in mind that 'appliances-must be built to withstand a great deal of use and abuse by persons with 'a relatively limited knowledge of mechanical contrivances and must also be built lto be absolutely. safe when carrying the customary load oi 110 v. of electric current. 'ligt' only must these qualities be built intosuch an appliance but in so doing, the cost `of manufacture must be kept as low as possible due to keen competition in the trade and because'oi this condition even minor improvements, the utility of which may vat first glance be deemed somewhat obvious, are often Vthe result of many months of painstaking research to 'enable the manufacturer to take advantage' of every possible simplification of his device while still building init the requisite qualities Iof durability, safety and convenience. Y

In accordance with these aims and objectives, .thenovel structures andr attachments forming the subject-matter of this invention are shown incorporated in an electric sadiron which presents many of the problems above referred to and vwhich has been thesubject of a great deal of development in recent' years. A sadiron because' of electrical appliancesand particularly household its weight must be especially lrugged in construction and the handle used to manipulate it must be attached in sucha manner that itl willnot readily become loosened during use and also must be insulated to guard against the very high temperatures present in the base or sole plate.

l'Ihe electriciron shown in the accompanying ydrawing is provided `with a `base A, having a handle B for-manipulating it, which is attached to the base -by means of-a bracket C at the for--l wardpart landa corresponding bracketD atthe rearward part of the appliance.

'I'hek base A comprises a customary sole plate I0 upon which is positioned a weight Il securely held thereon by suitablescrews/fand a shell or casing- I2 'secured to the weight k,by means oi a pair of screws, not shown. Imbedded in the sole plate are coils I4 'of a heating velement which are protected by a cover plate I5. The shell itself extends toward the rear of the iron in the form of a heelrest L6, arranged to engage with a plate l1 when in assembled position-which in turn supports a series of contact strips as shown at 2li in insulated relation thereto.

A cord zz carries the electric wires 24 and 'ze by means oi which current enters the-iron. .The

iron maybe kequipped with a conventional type The handle B, which hasbeen previously deb scribed, is connected to the appliance by means of brackets C and D, and is itself/composed of a through which the 'strips sliown at 2! 'pass im:`

handle grip portion. which is rounded vland y shaped to fit the grasped handy ofa user. `The gripy tapers toward the rear, terminating in an extension Il which, when the iron is tilted in an upended position, `serves as a support together with the heel rest Il in orderto holdthe hot sole plate 'upward out of contact with an ironing board.`

At the forward end of the grip there is an elongated recess and in it is vinserted the upper f endll of the bracket C. 'I'his bracket is composed oi three resilient strips bound together at @the upper end Il and at thelower end lll where.

they are secured to the casing by a rivet 92. At

Fr'om they foregoing description it will beper- -ceived that #manynovelties in construction have been incorporated into an electric appliance here embodiedin an electric sadiron. The advantages in constructionzit is believed have been clearly pointed kout and again Vemphasis is laid on their extreme simplicity and time-saving characteris- ,V tics from the point of View of manufacture. In addition to this-it'will be seen that' every attempt possible has been made to provideanelec--V tric appliance well insulated in order t protect a user and at the same time oi rugged and"dur l ableconstruction'. 1 l'I'he structure` shown and described has Amadepossible 'a householdappliance particularly 'convenient and `easy to handle `and one extremelywell adapted to modern demands `for, an emcient instrument 'of its sort.`; l
